SUMMARY
Neocypholaelaps apicola n. sp. is described from specimens found in brood combs of the Indian honey
cerana indica Fabr., from Pakistan.
A list of known species of Neocypholaelaps is
included. Adult bees were found infested also by the tracheal mite, Acarapis woodi
(Rennie). Dermatophagoides pteronyssinus (Trouessart), a house dust mite responsible for house dust
allergy or asthma, is reported for the first time from the brood combs of A. cerana indica.

Samples of brood combs and diseased Indian honey bees (Apis cerana indica
Fabr.) were received recently from Mr. Rafiq Ahmad of the Pakistan Research
Council, Honey Bee Management Project, Islamabad, Pakistan. They had been
sent to Dr. H. Shimanuki of the Bioenvironmental Bee
Laboratory, P.P.I., U.S.D.A.,
Beltsville, Maryland, for diagnosis of honey bee diseases, parasites and
pests. Upon examination, the bees were found to be affected by the acarine disease
caused by the tracheal mite, Acarapis woodi (Rennie). The brood combs were found
infested also by a new species of Neocypholaelaps described here. The mites were
present in considerable numbers, but it is not known these mites are causing trouble
in beehives. Dermatophagoides pteronyssinus (Trouessart), a house dust mite
responsible for house dust allergy or asthma, was found in the brood combs of A.

Members of the genus Neocypholaelaps occur on bees, in hives, on certain
Lepidoptera, and on various tropical and subtropical flowers. The are probably
pollen feeders; the unmodified chelicerae suggest non-parasitic feeding habits, the
relationship between the mites and insects being one of phoresy. The mites use the
insects chiefly as means of dispersal. Six of the ten known species of the genus are
associated with honey bees (Apis and Trigona); see list of Neocypholaelaps
species. Mites associated with honey bees have been reported as being troublesome
in hives. Two species, Tropilaelaps clareae Delfinado & Baker and Varroajacobsoni
Oudemans, are serious pests of honey bees. Any mite found associated with honey
bees should be regarded with significance.

other species by the form of setae on the dorsal shield : setaeia are minute in the adult

chaetotaxy occurs on femur I, which has 11 setae on apicola, 12 on other
species. The male anal shield is unique in form, being kidney-shaped.
